I literally never cared about "scores". Just the narrative and characters as well as the epic battles. I think playing this game and focusing on the best way to get high scores is like trying to use a pizza as a windmill/kouga shuriken, sure, you "could" try and do that, but the point of pizza is to exist as food and not as projectile weaponry.
You can always just redo stuff if you wanna min and max or time attack or what have you but the game really isn't about those types of things. It's about a heartfelt war epic and cool strategical battles.
For example, there's this one stage in VC1 where Selvaria is an enemy but not the objective so you are tasked to bypass her and destroy this very large tank. Her attacks as you walk around however will intercept you and kill off most units pretty fast. My way of going through that battle was absolutely hilarious. Selvaria's attacks, you see, would not harm the tank at all, since she apparently counted as an infantry unit or something, so what I would do is use the tank as cover to transport my units through her firing area, by placing my units behind the tank so that it'd block her fire and moving them only from the rear end of the tank to the front end, ending the turn, then moving the tank far enough where it'd still cover them with it's rear end (which was not very far at all, it was basically distance equal to the length of the tank), and then ending the turn prematurely again and going back to the units. I would do this over and over for I don't know how many turns in order to get them from one part of the stage to the other and I'm sure it did negatively impact my "score" but that gaming moment has stuck with me as one of my most ingenious and hilarious ideas I came up with in any game ever.
